sa su ,freely over the side seam of the can-body` :The lever -1 bearswith its upper 'side against 'hearing A3, while the lever-section k issupported u on a fixed abutment A5. -In this way .the evers j and 7c 7care prevented from artaking in the axial movement of spindle i. Aheroller g4 by engaging Groove l swings the free end o lever j, as well asof lever k c, to

' assume a position corresponding to the conis engaged by the 'outerface of a horizon-y tally-movable wedge k, slidable within alongitudin'al groove k7 of lever-section k. To wed e 7c, is piv'oted atm one end of a link m, c onp ed by pin nl to a secondlink n, the wholeconstituting a toggle. Link n is pivoted to lever-section 7c', as at n?.Upon pin n isree to'l turn a roller 0, which is adapted to ride,

uponv a disk o', rigidly secured to spindle i.

. -Leveis and k k are connected by a spring p,

enga pin j of lever 7'y and a pin lcoi'v leversectionf. The rotation ofcam h3 will cause i a-vertical reciprocating movement of spindle 'i' anddisk .0.

. joint m n, thus causing the wedge k"` to be advanced. (See arrow 1nFig. 3.) When disk o lowered, it will allow toggle-joint rmy 'n tobefcontracte'd, thereby retracting wedge 7c, The wed e 7c in advancingwill crowd lever 7c k awa yom roller j, so as'to press seamingrolleragainst the can-body and. verform the seaming operation. When the' isk ois lowered, thewedgc 7c*l is retracted to permit s ring p to swingroller K off the can-body B.

he camsh.3 h3 are so set that the rollers K KI are consecutively broughtinto engagement with the can to he headed. In this way the rst rollerstarts the'seaming operation,while the. second roller 'completes thesame, as usual.

`IIand-lever. g, which servesto raise plat# form f 2, also serves tostart the machine and to open the-brake in the following manner: Lever gis provided 'with a depending arm g5, to which is pivoted one4 end of' arod p, the other cnd'of which is connectedto an elbowlever r, pivoted toframe A at r. To the lower arm of lever r is journaled at r2 a rollerr3, en aging cam h2 of shaft h. The upper arm of, ever r is by rod sconnected lto a double lever t, pivoted at t to frame A. This lever en'ages a groove b3 of the movable member 4 of clutch b bwhich may be of.any suitable construction. Lever t is by rod u further connected to abrake-lever o, pivoted at 'v' to frame A and inluencedby a spring v2.Lever v engages the brake-shoe When said disk is raised, it. .willroller o, and thereby distend togglefw of a brake-disk w, fast on shaftb. It will4 f be seen that. by Adepressing hand-lever y iloller rawillbe lifted out of notch h4 'of cam 2 lowered to close clutch b band thusstart the machine, while the brake w w is simultaneously opened by theengagement of notch v3 of lever v with the tailpiece' w2 of brakeshe w.When the machine is started,

roller r3 will' ride along the convex edge h5 of' cam. 'LZ, and thusprevent the clutch from opening, even after hand-lever g has beenreleased. Aiter cam-shaft h has made a complete rotation roller r3 willenter recess h4 b3' the combined action of the springs g- 122. In

this waT lever r will tilt levers g, t, and u to lower p atform f2 andopen clutch b b4 and also to'set' the brake. l

It will be seen that with my machine the 'guide-levers y' andseeming-levers 7c 7c turn on coincident pivots, so,` that ltheseamingrollers and guide-rollers describe an arc struck oi from a commoncenter and by an equal radius. The result is that. the seaming-rollerswill be so set as to conform accurately to the contour'of the can andform. a perfect seaim, which faction'is not attainable when'theguide-levers and the seaming-levers turn on differently-positionedpivots.

What I claim isA 1. In a can-heading machine, a guide-lever, aseeming-lever, a spindle on which both levers are ulcrumed, aseaming-roller carried by the seeming-lever, and means for operating thelevers, substantially as s ecied.

2. In a can-heading machine, a guide-leverand a seeming-lever havingcoincident pivots, a cam engaged by the guide-lever, and

Further, the clutch member b4 will be IOO means for operating theseaming-,leven substantially as speciiied. l

8. In a can-heading machine, a guide-lever, a seeming-lever, a spindleon which both levers areyflcrumed, a, cam engaged by the guide-lever,and a horizontally-slidable wedge adapted-'to operate the seeming-lever,substantially as specified.

4. In a can-heading machine, aguide-'lever, a seaming-lever, a spindleon which both levers are fulcrumedfa wedge between the levers, and meansfor operating the wedge, substantially as specified.

5. In-v a can-heading machine, a guide-lever and a seeming-leverhavingcoincident, pivots', an abutment on one of said levers, and awedge between said abutment and the other lever, substantially asspecified.

6. In a can-heading-machine, a guide-lel yver and a seaming-lever havingcoincident pivots, a pin on one of said levers', a roller on said pin,and a wedge'between said roller and 1 2 5A the other lev- 'isubstantially as specified.
